Conclusions
-
1.
The electrical resistance of heat-resistant nickel alloys in the temperature range of dissolution of the γ′-phase is determined primarily by the volume share of γ′-phase and its specific electrical resistance. In dissolution of the γ′-phase the specific electrical resistance of the alloys drops.
-
2.
The temperature of the start of dissolution of the γ′-phase does not depend upon the change in content of the alloy elements and is 855±10°C. An increase in the alloy of the aluminum, titanium, and niobium contents leads to an increase in the temperature of complete dissolution of the γ′-phase, while a change in the chronium, cobalt, and molybdenum contents has practically no influence on it.
